Safe Ammonia Storage Systems for Decarbonizing Commercial Shipping Fleets

transportPilotedTRL 7

Imagine turning a giant ship's fuel tank into a high-tech thermos that can safely hold ammonia, a clean alternative to oil. The team built these tanks using both steel and advanced plastics to make sure they don't leak or break. They also created a digital tool that acts like a calculator to help ship owners figure out exactly which tank fits their specific vessel.

The business problem

What needed solving

Shipping companies face immense pressure to decarbonize but lack safe, certified, and scalable ways to store ammonia on board. Existing tanks often don't fit diverse vessel types or meet strict safety regulations.

The solution

What was built

Fabricated and tested metallic and composite NH3 tanks and a digital platform for designing fuel systems. They also created a full-scale retrofit engineering plan for a 31,000 DWT vessel.

Who can put this to work

Maritime Shipping
enterprise
Target: Ship Management Company

If you are a ship manager dealing with strict carbon emission limits — this project developed a retrofit design for a 31,000 DWT vessel that allows the use of ammonia as a clean fuel. This enables a transition to zero-emission shipping without building entirely new fleets.

Shipbuilding
enterprise
Target: Shipyard

If you are a shipyard dealing with the lack of standardized ammonia storage designs — this project developed modular steel and composite tank configurations for 1,000 m3 of liquid NH3. This provides a blueprint for building new, compliant, green vessels.

Marine Engineering
SME
Target: Naval Architecture Firm

If you are an engineering firm dealing with complex safety calculations for new fuels — this project developed a digital platform to assess installation requirements based on ship size and power demand. This reduces the time and risk involved in designing fuel systems.

Frequently asked

Quick answers

What is the cost or price of implementing these tanks?

Based on available project data, specific pricing for the tanks is not provided, but the project included a techno-economic evaluation to prove commercial attractiveness.

Can this be scaled for different ship sizes?

Yes, the project developed modular and scalable configurations and conducted studies for five different vessel types, including bulk carriers, tankers, container ships, RoPax ferries, and inland passenger vessels.

Who owns the IP or how is licensing handled?

Based on available project data, licensing details are not specified, but the project resulted in New Technology Qualification and Approval in Principle by the IACS Classification society.

Does this meet current maritime safety laws?

Yes, the project focused on regulatory framework evolution and developed updated technical rules to strengthen regulatory acceptance and safety guidelines.

How long does it take to integrate these systems?

Based on available project data, the project provided a digital platform to assess installation requirements, though a specific installation timeline for the 31,000 DWT vessel is not listed.

Consortium

Who built it

The consortium is heavily industry-driven with a 69% industry ratio, comprising 9 industrial partners and 4 SMEs. This strong commercial presence, spanning 6 countries and 13 total partners, indicates that the technology was developed with direct market application and operational viability in mind rather than purely academic interest.
